This invention relates to a method and m'eans of singeing fabric, yarn, and the like in which meansare provided for singeing both sides of the fabric by having both? sides of the fabric treated by the singeing operation at the same time.

An object of this invention is to provide means for singeingfabric, yarn and thelike having singei'ng devices located above and below the fabric; yarn and the like, said singeing devices being adjustable withrelation'to each other and also being adjustable as to angularity so as to bend the cl'oth to form a'combustion chamber on both' sides of the cloth and also to bend the cloth to occupyja plane having an oblique angle on the surface at the point where it is exposed to the greatest amount of flame. This causes the cloth to form an angle of more than 180 degrees I to spread apart any projecting fibers so they will be morethoroughly singed. It also opens the pores'of the goods and exposes the nap to burn the same away more perfectly,

Another object of this invention is to provide means for singei'ng both sides of'the fabric si multaneously by causing a combustion chamber tobe' present on both sides of the fabric with means for allowing the inert and burning gases to escape from" the outer edges of the combustion chambers and thus avoid any back pressure in the burning gases.

nether object of theinvention 'is to provide a like, inwhich the. space-between the Walls of the I combustion chamber and'the fabric, yarn and the like passing thereover may be changed at will: whereby the proximity of the 1fabric,--yarnp 56 and: the likef tol the; flame may-be adjusted and alsoi the: intensity of the heat may 'be regulated. Some of the objects of the invention having beemstatedLJQtherJQliiects will appear as'the description proceeds when taken in connection with the accompanying drawings, in which.

singei'ng apparatus for cloth in which combustion chambers are formed having means for al-, lowing escape of some of the flames from the combustion chambers to impinge on the cloth to partiallysihge the same before its surface is exposed-tothecombustion chamber. 'By allowing Figure 1 isa'plan view of the singeing apparatus;

Figure 2 is an elevation of ore 1;'

Figure 3 is a transverse sectional view taken along line 3-3 in'Figure 1;

Figure 4 is an enlarged transverse sectional view taken thru the burners;

. Figure 5 is a plan view of the nose portion onthe long wing of the burner;

Figure 6 is a sectional view takenalong line- 66 in Figure 5; i

Figure 7 is a modified'form of the nose -por-' tion on the long'wing of the burner;

Figure 8 is a sectional view taken along line 8--8 in Figure 7;

Figure 9 is another modified form of the nose portion on the long wing of the burner.

Referring more particularly to-the'drawings the numerals 10 'and 11 denote the supporting frame members for'the singeing'machine upon which are mounted suitable brackets12 and13 provided with'bearings" 14 and 15, supporting each end'of the lower burner 17. The lower part'of burner 17 is a shell 'portion, circular in" cross-section into which a suitable gas pipe 18 is inserted. Thispipe 18' has perforations 19 on the lowerside which allow the gas to: es"- cape'from the pipe into a space'20' and up'thru perforations 21 where it is ignited to singe the lower side of clothorfabric 22; It will be noted that bearings 14 and 'h'ave suitable set screws 23' and 245 which serve as an adjusting means for the lower burner 17' when it is desired to turn the burner at different positions inthe. bearings, thereby getting the cloth bent at'the proper angle to insure best singeing results.

Theupper portion of burner 1'7 has an'angu larly disposed member-25 which extends outwardly and upwardly and has an enlarged. nose portion; 26 on the end thereof, said nose portion having a suitable bore 27 thru which water is circulated to prevent this member from becoming overheated and damaging the fabric as it slides over this portion. Another angularly disposed member 28 is'providedon the other side of the upper portion of burner 1'7. Likewise, this member extends outwardly and up-- wardly and has on the end thereof an enlarged nose. portion 29 which has suitable angularly disposed grooves 30 which provide means for the left end of Figthe dead or inert gases to escape from the" I tions.

41 respectively. In these bearings a transverse rod 42 is mounted, having suitable operating Wheels 43 and 44 and beveled gears 45 and 46 which are adapted to mesh with beveled gears 47 and 48 respectively mounted on the upper end of vertically disposed threaded shafts 49 and 50. Threaded shafts 49 and 50 are threadably mounted in sliding members 51 and '52 in brackets 38 and 39 respectively. These sliding members have'extended portions 53" and 54 in which are mounted the ends of the upper burner 55. I

It is seen that by'turning wheels 43 and 44 that shafts 49 and 50 are turned, which in turn raises or lowers members 51 and 52 which support the upper burner.:, By this method the adjustment of the vertical distance between the two burners is made.

The upper burner 55 is identical in structure to the lower burner 17; however, the burner is turned in an upside down position in order to singe the upper side of the cloth at the same time the lower side isbeing singed by burner 17.

The upper part ofyburner 55 is a shellportion,

circularin cross section; into which a suitable gas pipe'56 is'inserted. This pipe 56 has perforations 57 on the upper side which allow the gas to escape from the pipe into a space 58 and down thru perforations 59where it is ignited to singe the upper side -of the cloth 22.- It will be noted that suitable screws 60 and 61 are pro-,

vided in members 53 and 54 to serve as an adjusting meansfor the upper burner 55 when it is;desired to turn the burner at different posi- -The lower portion of burner 55 has an angularly disposed member 65 whichextends outwardly and downwardly and has an enlarged nose portion 66 on the end thereof, said nose portion having a suitable bore 67 thru which water is circulated to prevent this member from becoming overheated. Another angularly disposedmember 68 is provided on the other side ofthe lower portion ,of burner 55. Likewise,

this member extends outwardly and downwardly and has on the end thereof an enlarged nose portion 69 Which has suitable angularly disposed grooves 70 which provide means for the escape of dead gases as previously described.

A plate 71 is secured to the upper portion of member68 by any'suitable means such as screws 72 forming a space 73 thru which water is circulated to ,;cool member 68. It will be noted that the coolwater enters the upper burner 55 thru pipe 7 6' and circulates thru bore 67, pipe '17 and into space 73 which has an outlet such as a pipe 78.

Figure 7 shows a modified form of the nose.

portion on the long wing of the burners in which a plurality of holes 84 are provided for the escape of the dead gases. 7 I

Figure 9 is another modified form of the nose portion on the long wing'of the burners and 11 are in which a plurality of slots 81 are provided for the escape of the deadgases. n

It is seen that in case agreater' bend is desired to be given to the 'cloth as it passes over nose portions 29 and 69 that the upper burner 55 can'be raised vertically and a greater angular adjustment can be imparted to the burners by set screws 24; 23, 60 and 61 and in this way the angle of bend in the cloth can be adjusted, as the greater bend in the cloth allows more complete singeing, especially where a great amount of singeing is necessary to a fabric.

While I have described and shown the bumers as being disposed above and below the fabric and the like, it is understood that the invention contemplates other positions whichitheburners' may occupy as I have found that equally good, results can be accomplished by having the longi-, tudinal axis of the burners disposed in a vertical. plane: ..1 y In the drawings and specification there has been set forth a preferred embodiment ofthe invention and although specific terms are em. ployed, they are used in a generic and descriptive sense only and not for purposes of 1imitation, thescope of the invention being set forth; in the appended claims. 1 1.
